TOBACCO FEEDING AND DRESSING IVIECHANISM.

SPECIFICATION forming part of LettersPatent No. 578,740, dated March 16,1897.

Application led January 29, 1896. Serial No. 577.299. (No model.)

To all whon'z, t may concern:

Be it known that I, J osErH F. HARTIGAN, a citizen of the United States,residing at VVashingtomin the District of Columbia,have invented certainnew and useful Improvements in Tobacco Feeding and Dressing Mechanism;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to malte and use the same.

My invention consists in the novel features of construction andcombination of parts hereinafter fully described, reference being had tothe accompanying drawings, which illustrate one form in which I havecontemplated embodying my invention, and said invention is fullydisclosed in the following description and claims.

Referring to the said drawings, Figure l represents a portion of acigarette-machine, showing the tobacco-carrying belt and my improvedtobacco feeding and dressing apparatus. Fig. 2 is a side view of thetobacco feeding and dressing mechanism. Fig. 3 is a vertical sectionalview of the same on a plane transverse to the line of travel of saidtobacco-carrying belt.

In the drawings, A represents a portion of the framework of acigarette-machine, and B represents a horizontally-disposedtobaccooarrying belt which receives the tobacco from the feeding anddressing device and delivers it to devices for forming a tobacco rod andcovering the same with a suitable wrapper, of which devices the belt Bmay in some instances form a part.

O represents the framework which supports the parts of tobacco feedingand dressing devices, and is supported upon the frame A of thecigarette-machine and preferably extends transverselyhereof.

D represents the receiving-belt of the feeding and dressing devices,supported by suitable rolls d and d', mounted in the upper part of theframe C, so as to hold the upper lap of the belt in a horizontalposition. Adjacent to the roll d and slightly above the same is thefeeding and compressing roller E, between which and the belt-roll d thetobacco is fed, and a brushing-roller F is mounted in frame C adjacentto the roller d for brushing the tobacco downwardly. from the belt D asit passes around the said roll d. I prefer to employ for this purpose acylinder provided with backwardly-bent wire teeth, as shown, similar toa carding-cylinder, but I do not limit myself to this construction, asother forms of brushing-rolls may be employed for this purpose.

Beneath the brushing-roller F is an intermediate or spreading belt G,supported by rolls g and g in such a position that the upper side of thespreading-belt G is substantially parallel to the lower side of belt D.I prefer to make the supporting-roll d' of belt D larger in diameterthan the roll d, so that.

the under side of belt D lies in an inclined position, and by making theroll g larger than the roll g the upper face of spreadingbelt G will lieparallel to the lower face of belt D, while the lower part of belt Gwillbe substantially horizontal. The spreading-belt G is driven much morerapidly than the belt D, and adjacent to the roll g is a feeding andcompressing roller H, which is placed nearer the roll g than the rollerE is to the roll d, for a reason appearing hereinafter. Adjacent to theroll G is a brushing-roller K, similar to the roller F, for brushing thetobacco downwardly from the belt G.

Below the roller K is the delivery-belt L, which is supported upon therolls Zand Z and preferably has its upper side parallel to the lowersideof the belt G and in a substantially horizontal position. Adjacentto and above the roll Z is a feeding and compressing roller M and thebrushing-roller N, similar to the brushes F and K, and below the brush Mis a hopper O, into which the tobacco is delivered by the brush.

The hopper O has its discharge-orifice just above the belt B of thecigarette-machine, so that the tobacco is delivered upon the latter. Thedelivery-belt L is driven at a slower speed than the intermediate beltG, the driving mechanism for the several belts and other moving partsbeing indicated in Fig. 2, but any other preferred arrangement of belts,Tc. for driving the parts can be employed that will give the propermovements to the said parts.

The operation of the device is as follows: The tobacco is spread by theoperator in an IOO even layer upon thetop of belt D and is graduallymoved toward the rollers E and F, passing under the feeding-roller E,after Which it is brushed down upon the rapidly-moving.

speed than the spreading-belt G the tobacco, f

now thoroughly loosened 'by two successive brushings' and by beingspread thinly upon the 4 belt G, collects upon the belt L and is fedalong by it in a thicker layer than thatupon belt i The tobacco thenreceives its fl-nal com-g pression under roller M and is then brushed fdown into hopper O tothe carrying-belt B by a for driving said spreading-belt at greater It Will be seen that by employing a feeding i andcompressing roller adjacent to each brush the tobacco Will be heldgently between said compressing-roller and the belt, and the brush willthus exert a combing action,which tightens up thetobacco and prevents itfrom passing on in a lumpy or matted condition, andas this operationisvrepeated several times fthe tobaccoV is in a very even and lightcondition i the brush N.

when it is iinally delivered to the belt B.

Vhat I claim, and desireto secure by Letters Patent, is-

l. In a tobacco feeding and dressing mechanism, the combination with thetobacco-rej ceiving belt and acarding-roller therefonof a spreading-beltadapted to receive the tobacco from said carding-roller, meansfordrivingsaid belt ata greater speed than the receiving-belt, acarding-roller'for said spreading-belt, aV delivery-belt adapted toreceive the tobacco vfrom the carding-roller for the spreading-belt, andmeans for driving said delivery-belt at a lower rate of speed than thespreading-belt to accumulate the loosened tobacco upon thedelivery-belt, substantially as described.

2. 'In a tobacco feeding and dressing mechanism, the combination Withthe receivingbelt, a compressing-roller and a carding-roller adjacent toits delivery end, the spreadingbelt adapted to receive tobacco from saidcarding-roller, a compressing-roller adjacent to the delivery endof saidspreading-belt located closer to said belt than the distance between thereceiving-belt-andits compressing-roller, a carding-roller for saidspreading-belt, means speed than the receiving-belt, a delivery-beltadaptedto receive the tobacco from said card- .ing-roller for thespreading-belmmeans for driving the receiving-belt at a lower rate ofspeed than the spreading-belt'to accumulate the'loosened tobacco uponsaid receiving-belt, and a compressing-roller for said delivery-beltlocated closer thereto than the distance between the spreading-rollerand its compressing-roller, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

JOSEPH F. HARTIGAN.
